PERFORMANCE OF A BIOGAS RUN PETROL  ENGINE FOR SMALL SCALE POWER GENERATOR

PERFORMANCE OF A BIOGAS RUN PETROL  ENGINE FOR SMALL SCALE POWER GENERATOR

The use of biogas as an alternative fuel in a 1.5 kW portable electric generator run by a SI (spark ignition) engine was studied, keeping engine modifications to a minimum. The biogas was produced synthetically using a mixture of line supply of natural gas and a regulated flow of carbon-di-oxide from a cylinder. The engine performance was studied using proportional mixtures of the two gases having 55%, 60%, 65 % and 70 % methane contents by volume that simulate a range of biogas sources. Maximum output power was reduced by 20 % with biogas having about 60 % methane content. The brake specific fuel consumption (bsfc) values were comparatively high due to CO2 in biogas but overall peak efficiencies were comparable with petrol. Such performance with a reduced maximum load capacity was only possible if the methane content of the biogas used were 60 % or more. The findings of this study may have potential significance regarding small-scale power generation in agricultural and poultry firms, using biogas plants
